Born in Brunei, raised in Holland, and schooled at the esteemed Central Saint Martins in London, New York-based Sander Lak debuted his women’s ready-to-wear brand Sies Marjan in 2016. Named after the founder’s parents, the label takes a spirited approach to fashion, working colorful, expertly draped fabric into fluid dresses and relaxed shirts. Lak, a former designer for major fashion houses in Europe, has become the go-to source for thought-provoking, elevated looks.
